== Highlights== * Rare Character Search? Have you ever wanted to search for "rare" characters on-wiki—like the Ankh (☥), unusual punctuation like a ditto mark (〃), or uncommon whitespace characters like an 'en space'? We're trying to gauge interest in a potential future feature that would make finding them easier. Join the conversation on Phabricator [0], English Wikipedia or Wiktionary, or Commons (links at [1]).
